doc.: IEEE 19-08-0024-01-0000 Submission July 2008 Alvarion Some simulation results for 802.16h CX-CBP in 3.65GHz Notice: This document has been prepared to assist IEEE 802.19. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor grants a free, irrevocable license to the IEEE to incorporate material contained in this contribution, and any modifications thereof, in the creation of an IEEE Standards publication; to copyright in the IEEE’s name any IEEE Standards publication even though it may include portions of this contribution; and at the IEEE’s sole discretion to permit others to reproduce in whole or in part the resulting IEEE Standards publication. The contributor also acknowledges and accepts that this contribution may be made public by IEEE 802.19. Patent Policy and Procedures: The contributor is familiar with the IEEE 802 Patent Policy and Procedures, including the statement "IEEE standards may include the known use of patent(s), including patent applications, provided the IEEE receives assurance from the patent holder or applicant with respect to patents essential for compliance with both mandatory and optional portions of the standard." Early disclosure to the TAG of patent information that might be relevant to the standard is essential to reduce the possibility for delays in the development process and increase the likelihood that the draft publication will be approved for publication. Please notify the Chair as early as possible, in written or electronic form, if patented technology (or technology under patent application) might be incorporated into a draft standard being developed within the IEEE 802.19 TAG. If you have questions, contact the IEEE Patent Committee Administrator at.http:// ieee802.org/guides/bylaws/sb-bylaws.pdfpatcom@ieee.org Date: 2008-27-09 Authors:

doc.: IEEE 19-08-0024-01-0000 Submission July 2008 Alvarion Synchronization CX-Frame is synchronized with GPS-like time source –802.16h-based systems are using CXSBI in a synchronized mode Sync of 802.11y with CXCBI is not mandated Two operational modes –Sync. CX-CBP The 802.11 AP limits the 802.11y operation to CXCBI –See Annex in “Parameters for simulation of Wireless Coexistence in the US 3.65GHz band” document –Un-sync. CX-CBP No limitation is imposed
